Replace Your Batteries and Avoid Any Risk to Your UPS

Batteries are critical for any UPS system to work and fundamental for power to continue running in the event of a mains failure.

Although regular maintenance and inspections can extend the working life of UPS batteries, they will eventually need replacing. Specialist Power Systems offer a comprehensive UPS battery replacement service to suit you.

We can design your battery installation ensuring that the systems employed take in to account all key aspects of your battery requirement. Considerations will involve:

  • Space Planning
  • Autonomy time
  • Environmental conditions
  • Battery Type
  • Electrical Design infrastructure & protection

What Our Experts Say About When to Replace Your UPS Batteries

All lead acid batteries are prone to natural decay and depending on your make and model, most batteries have a design life of between five and ten years. To avoid any unnecessary and costly downtime should you get a mains power failure, our experts recommend changing batteries as follows:

  • Every 4 years for a 5-year battery life
  • Every 8-9 years for a 10-12 year battery life
